SPINNING, DOUBLING, AND TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 242,060, dated May 24, 1881.

Application filed April 27, 1880. (No model.)

To all whom it may concern Be it known that we, FRANCIS SEYMOUR and AUGUSTUS BANNIGAN, of Paterson, Passaic county, New Jersey, have invented a new ment in the class of silk doubling and spinning machinery in which afaller-wire is hung by its eyelet end to the thread, and with the break age of the latter falls upon the arm of a balance-lever and actuates a detent. In our invention the action of the spinning and doubling devices is arrested when a thread breaks by the depression of a spring-lever, which operates by gravity upon other devices so arto loose whirls or pulleys.

ranged as to raise or depress the bands of the several spindles, and thus shift them from fast with this operation and result the doubled thread is removed from between the drawingrolls by the-action of the doubling device,

the doubling and twisting devices.

which is suitably connected with the bandshifters.

The invention consists in the construction, arrangement, and combination of parts, as hereinafter described and claimed.

ln accompanying drawingsflbmning part of this specification, Figure 1 is a front elevation of our improved machine. Fig. 2 is a sectional elevation of the same, showing also the arrangement of the threads in connection with Fig. 3 is a plan view of a portion of the machine. Fig. 4 is a perspective view of the band and shifting mechanism. Figs. 5, 6, 7, and 8 are detail views.

The silk filaments or other fibrous material to be operated upon in our improved machine is taken from bobbins placed on the pins 0 of the jack-board p, when it is desired to simply double and spin it; but when it is desired ,to first spin and then double it, and finally respin it thus doubled, the material is taken from the bobbins or spools a a. It is unnecessary to Simultaneously.

make further reference to the use of the jackboard 1), it being a well-known feature in spinning-machines, and in this instance subserving no new purpose, nor involving a new mode of operation, since the fibrous material passes from the bobbins held by the pins of the jack-board to the same doubling-eye, and is subsequently acted on in the same manner as the material taken from the bobbins or spools a a. Such fibrous material is twisted as it unwinds from the latter, (by means of fliers or other suitable devices, which may be attached to their spindles or otherwise arranged in the usual way,) and passes thence to dragwires 0 0, around which it is wound; then over 6 the sustaining-rodsddat thetop ofthe machine; then'down through the fork of the doublingeye 2'. The two singletwisted threads, thus brought together or doubled, pass between the drawing-rolls e f, appearing on the front side of the -latter, and passing thence down to the receiving bobbin or spool a, and are simultaneously spun'and wound thereon, (its spindle being in practice provided with'ordinary appliances for winding on.) The spindles carry- 7 ing the spools a a and a are rotated by bands m m, which are caused to travel at the required speed by the large driving-cylinder n, around which they pass, as shown in Fig. 2. The

' spindles ofthe respective bobbins are provided with fast and loose pulleys a a Figs. 6, 7- that is to say, with a whirl, a and loose pulley a In case of spools a, Fig. 7, the fast pulleys or whirls proper, a are placed below the loose pulleys a and in the case of spool a, Fig. 6, the fast whirl a is above the loose one (1 for a purpose that will presently appear.

Intermediately of the cylinder n and the spindles of spools a the bands at m pass over the cylinder at, Fig. 2, by which they are prevented from turningor twisting-that is to say, they are held fiat on the whirls to facilitate the action of the shifting devices, which we will now describe. As before intimated, we shift 5 the bands from the said fast to the loose whirls, and thereby arrest the rotation of the spools and the operations of doubling and spinning in case a thread breaks. Such arrest of action depends primarily on the position of the pivr00 oted fallers or faller-wires 1'. They are pivoted to a bracket, fixed on the frame of the machine, and their free ends are normally upheld by the tension of the filaments or threads, which is incident to the action of the drawing-rolls e and f. If a thread breaks under the strain to which it is subjected, the faller-wire through whose eye it passes instantly drops upon one ofthe lateral arms, It, ofan elbow-lever, h, Figs. 2 and 4, which is pivoted at the apex of its angle to the frame of the machine. The weight of such fallerwvire overcomes the tension of a spiral spring, g, and tilts the lever downward into the position shown in dotted lines, Fig. 2. A rod, p is attached to the longer horizontal arm of lever h by means of a screw that passes through the vertically-c1011gated eye of said rod, and the lowerend of the latter is pivoted to a link or block, a", to whose lateral extremities are pivoted levers c, which are fulcrumed on fixed pivots so as to vibrate in a vertical plane. The above-described depression of the lever 71 causes the rod 1) to carry down the block 0 and thus simultaneously tilt thelevers 0, thereby elevating their broadened outer ends, 0 Fig. 2. In such operation the link 0 falls upon the middle belt, m, and shifts it from the fast whirl a of the spindles, carrying bobbin (1. down onto the loose pulley or whirl a and the levers 0 simultaneously shift the outer belts, in, upward onto the loose pulleys a of the spindles carryingbobbins a, thus arresting the spinning and doubling operation, as before stated; but it is obviously necessary to also arrest the action of the drawing-rolls e f upon the threads at the same time, and for this purpose we pivot the doubling-eye i to a fixed portion of the machine, and provide it with a lateral arm, which is connected with the rod p by a link, Ir, Figs. 2, 4. It hence results that when the lever h and rod 1) descend, as above described, the tension on link k turns the doubling-eye i on its pivot, Fig. 8, and thereby carries the thread laterally out between the portions of rolls cf which are in contact into the space beneath the reduced end of the upper roll,'e, so that it is no longer drawn forward.

In respect to details, it should be stated that the spring 9 is attached to the vertical portion h of lever h at a point slightly in rear of its pivotal bearing, whereby the lever is held in the position shown in Figs. 2, 4. The tension of the spring is regulated and the sensitiveness of the lever h to downward pressure increased or diminished at will by adjusting the lower end of the spring in different notches of a rack-bar, 1), (shown clearly in Fig. 4,) as will be readily understood.

Instead of adjusting the lower end of the spring along the rack-bar, we may adjust the rack 1) higher or lower, and to this end the shank of the latter may be slotted, and a screw passed through the slot to secure the device to the frame.

In order to facilitate the action of the lever h and .nder it as rapidly effective as possible, we cut away the sides of its pivot h, as shown in Fig. 5, thus practically providing a knife-edge bearing, on which it is supported and tilted.

In order to vary the pressure between the rolls 6 and f as required for threads of different thicknesses, &c., the bearing of the upper roll, 6, is constructed with a vertical slot, to allow vertical adjustment of the same by means ofa thumb-nut, .r, Fig. 1.

The required vertical traverse of the dou bled thread while being wound on the spool a is produced by a cam, 1), Figs. 1, 2,6, on shaft b, which acts on a projection, b attached to a bar, r, which is adapted for vertical motion and guided by vertical rods 8.

The whirl a of the spindle of receiving-bobbin a rests on a tube or long collar, a, Fig. 6, and is thus held out of contact with the pulley M, which rotates loose on said tube. Thelatter is secured in the required adjustment by a set-screw, (1, (shown in Fig. 1,) which passes through the fixed rail b. The whirls a of the spindles of feeding-bobbins a being below the loose pulleys a, Fig. 7, thelatter require to be held up out of contact with the former; hence we secure the tube or collar a iinmovably in the rail 0 and' provide its lower end with a lateral flange, which is inclosed in a recess in the under side of said whirl. Oil is supplied to both spindles of bobbins are and a through holes in tubes a a The shaft b, cylinder a, and shaft 1), on which the drawing-roll f is mounted, are suitably geared together so as to revolve at the requisite speed.

What we claim is-- 1. The combination of the lever It, provided with arm h, with the spring g, cross-bar 7L fallers i, rack 12', connecting-rod 12 and bandshifters e 0 substantially as shown and de scribed.

2.
